Thank you for your inquiry. From what we gather from the question, you were asking about the specifics of PEP use, and if you should continue to use the PEP prescription that you have been given/renew your prescription due to the recent exposure you have had.
It is important to first acknowledge that PEP should not replace other highly effective preventative methods against HIV transmission. Condom use is extremely effective in protecting against HIV risk, and can result in a significantly reduced chance of HIV transmission.
As you have experienced another possible exposure, we would Recommend that you seek out your health care provider for additional HIV testing and a renewal of `your PEP medication. We are unaware of the effect that continued use of PEP may have, and how it may affect HIV transmission. For this reason, we maintain that seeking advice from a medical professional is advisable.
All the best,
AIDS Vancouver Online/Helpline, Cody
